any advice please on the best way to get from Euston to Clapham Junc with least amount of walking and train changes.
TfL's suggestion (via the routeplanner!) is:
EUSTON: 168, 88, 188 to ALDWYCH
ALDWYCH: 87 to CLAPHAM JUNCTION
Journey time approx 1h10!!!
It will cost more for a Travelcard
If you are just going from Euston to Clapham Junction and back then don't buy a travelcard, especially if you have Oyster cards. (I can't remember whether you've asked about Oyster before?) After 1600 on a weekday will cost £3.60 if you change at Vauxhall and returning later will cost £3.10 either way. The scenic route (via LO) is cheaper but will take ages. If you have a railcard logged on your Oyster then the return becomes £2.05, or probably less because you'll cap at the reduced off-peak zone 1-2 cap of £4.60.
Thanks for all your valued replies, time is of the essence as we are travelling down from Runcorn with a Megabus ticket, train arrives Euston about 16:00 and we head back home the same evening around 21:15. As it was only £4.50 for the 2 of us its worth going for a few hours spotting in London. It will cost more for a Travelcard
We are going midweek next week, looking at suggestions I will probably go Victoria or Vauxhall and then surface to Clapham.What day of the Week, as if your going Mon to Fri it may be better to get the Tube to either Waterloo or Victoria & change there rather than getting the bus through the Rush Hour.
